Earth Enhancement Material (Backfill Compound)
Ground electrode resistance is the resistance between a ground electrode or ground electrode system and remote earth. A low resistance ground electrode system is important in order to provide a low impedance path for the proper dissipation of lightning currents, and to protect personnel and equipment by minimizing and equalizing voltage potential differences. Both the National Electrical Code and the National Electrical Safety Code require the ground electrode resistance to be 25 ohms or less for facilities and systems1. Military Standards for grounding, bonding and shielding for communication systems require a ground electrode resistance of less than 10 ohms. Many telecommunications standards go beyond that, requiring a ground electrode resistance of 5 ohms (and sometimes even less). While there are many factors involved with ground electrode system resistance, the resistivity of the soil is a major factor for determining the final ground electrode resistance of a particular facility.
Our Earthing (ground) enhancement materials are high conductivity materials, which are designed to lower ground system resistance and improve grounding effectiveness in high resistivity soil conditions. They can be used in sites installed in areas with poor soil conductivity (such as rocky ground and sandy soil), or on sites where ground rod electrodes cannot be driven to the desired depth. They are also often used when limited space makes achieving the required ground electrode resistance impossible with conventional methods. We generally provide the Earth Enhancement Material also called Backfill Compound in 25 Kg bags.
